LOS ANGELES (AP) -- A judge says Chris Brown should remain in a rehabilitation facility and turned down a prosecutor's motion to have the R&B singer jailed over an arrest in Washington, D.C. last year.

Los Angeles Superior Court Judge James Brandlin says Brown appears to be making progress in a treatment facility and should remain there.

A prosecutor asked Monday to have Brown taken into custody over a misdemeanor assault case filed against Brown in D.C.

Brown remains on probation in Los Angeles over his 2009 attack on then-girlfriend Rihanna. Brandlin revoked the singer's probation in December but made no changes to his sentence during a brief hearing on Monday.
